react电商商品列表的实现流程详解
作者：是张鱼小丸子鸭
这篇文章主要介绍了react实现电商商品列表的流程，文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值，需要的朋友们下面随着小编来一起学习学习吧
整体页面效果
项目技术点
- antd组件库，@ant-design/icons antd的图标库
- axios 接口请求，拦截器配置
- node-sass sass-loader css样式的一个嵌套
- react-router-dom react路由使用
- react-redux redux
- hooks：大多数我们用的是函数组件，函数组件没有state属性，所以我们使用hooks来初始化数据，并且函数组件没有生命周期
拦截器的配置
由于我们登录成功之后，需要我们获取到token令牌之后，我们才能获取到数据，如果每个页面都需要获取一次token，代码比较啰嗦，所以我们配置了一个拦截器
需要授权的 API ，必须在请求头中使用 Authorization 字段提供 token 令牌
//配置拦截器
import axios from "axios";
//2. 创建对象
const Server = axios.create({
baseURL:"http://api.xiaohuihui0728.cn:8888/api/private/v1/",//基地址
timeout:5000,
})
//3. 请求拦截器
Server.interceptors.request.use((config)=>{
//前置拦截器请求发送出去之前触发
console.log(config);
//增加一个token值
let token = sessionStorage.getItem("token");
config.headers["Authorization"] = token;
return config;
},(err)=>Promise.reject(err));
//4. 响应拦截器
Server.interceptors.response.use((response)=>{
//请求成功，服务端返回数据到客户端之前触发
return response.data;
},(err)=>Promise.reject(err))
//5.抛出Serve对象的内容
export default Server;主页面
我们的数据写在columns里面，在里面的dataIndex绑定我们获取到的数据
const columns = [
{
title: '商品名称',
dataIndex: 'goods_name',
key: 'username',
},
{
title: '商品价格',
dataIndex: 'goods_price',
key: 'email',
},
{
title: '商品重量',
dataIndex: 'goods_weight',
key: 'mobile',
},
{
title: '创建时间',
dataIndex: 'goods_state',
key: 'role_name',
},
{
title: '操作',
key: 'action',
render: (_, record) => {
return (
<>
<Button type="primary" size="small" onClick={() => { showedit(record.goods_id) }}> <EditOutlined /> </Button>
<Button type="primary" size="small" danger onClick={() => { delGoods(record.goods_id) }} > <DeleteOutlined /> </Button>
</>
)
}
}
];
const [userData, setUserData] = useState([])
// 初始化数据
useEffect(() => {
getUserData()
setPage(1)
}, [search, page, pageSize])
// 初始化请求数据 用户
const getUserData = async () => {
console.log(pageSize);
console.log(search);
console.log(page);
let { data } = await axios.get(`goods?pagenum=${page}&query=${search}&pagesize=${pageSize}`)
console.log(data.goods);
if (data) {
setTotal(data.total);
setUserData(data.goods);
}
}
<Table pagination={false} bordered dataSource={userData} columns={columns} rowKey={(record) => record.goods_id} />添加商品
添加弹出对话框，添加里面有一个上传图片，我们上传的图片有一个单独的添加接口，所以我们使用action属性绑定我们要上传的路径，headres获取token，使用onChange获取图片上传的路径，然后在我们点击提交form表单数据时把图片临时地址添加成功
// 添加弹窗状态
const [addIsModalVisible, setAddIsModalVisible] = useState(false);
// 存图片
let [img,setimg] = useState("");
// 添加取消
const addHandleCancel = () => {
setAddIsModalVisible(false);
};
//获取token
let token = sessionStorage.getItem("token");
// 添加商品
const onAdd = async (value)=>{
console.log(value);
let pics = [{pic:img}];
let data= await axios.post("goods",{...value,pics})
setAddIsModalVisible(false);
getUserData()
}
//图片上传
const success = (info)=>{
if(info.file.status==="done"){
console.log(info.file.response.data.tmp_path);
setimg(info.file.response.data.tmp_path)
}
}
<Modal title="商品添加" visible={addIsModalVisible} footer={null} ref={addFormRef}>
<Form
name="basic"
labelCol={{ span: 4 }}
wrapperCol={{ span: 16 }}
initialValues={{ remember: true }}

<Form.Item wrapperCol={{ ...layout.wrapperCol, offset: 16 }}>

<Button type="primary" onClick={() => { (addHandleCancel()) }} danger>
取消
</Button>
</Form.Item>
</Form>
</Modal>
<Button type="primary" onClick={showModal}> <EditOutlined /> 添加商品 </Button>分页与搜索
我们在获取数据的时候，就获取我们的分页条数和总数以及搜索的关键字，然后在分页中进行数据属性的配置即可
// 搜索
let [search, setSearch] = useState("")
// 总条数
let [total, setTotal] = useState(0)
// 当前页
let [page, setPage] = useState(1)
// 每页条数
let [pageSize, setPageSize] = useState(2)
// 搜索
const onSearch = (val) => {
setSearch(val)
}
// 分页
const onChange = (page, pageSize) => {
setPage(page)
setPageSize(pageSize)
}
// 初始化请求数据 用户
const getUserData = async () => {
console.log(pageSize);
console.log(search);
console.log(page);
let { data } = await axios.get(`goods?pagenum=${page}&query=${search}&pagesize=${pageSize}`)
console.log(data.goods);
if (data) {
setTotal(data.total);
setUserData(data.goods);
}
}
<Search allowClear placeholder="input search text" onSearch={onSearch} enterButton style={{ width: 300, height: 60 }} />
<Pagination
className='pagination'
total={total}
showSizeChanger
showQuickJumper
pageSizeOptions={[10, 20, 30]}
defaultPageSize={2}
showTotal={(total) => `Total ${total} items`}
onChange={onChange}
/>修改商品
我们在点击修改弹出对话框的同时，需要把数据绑定到输入框内，我们利用formRef.current.setFieldsValue进行数据回填，然后请求修改接口即可
// 修改弹出框
const [isModalVisible, setIsModalVisible] = useState(false);
// 修改弹出框，数据回填
const showedit = async (e) => {
setIsModalVisible(true);
setgoodid(e)
let { data } = await axios.get(`goods/${e}`)
console.log(data);
formRef.current.setFieldsValue({
goods_name: data.goods_name,
goods_price: data.goods_price,
goods_number: data.goods_number,
goods_weight: data.goods_weight
})
};
// 修改取消按钮
const editHandleCancel = () => {
setIsModalVisible(false)
}
// 修改商品
const onFinish = async (values) => {
let { meta } = await axios.put(`goods/${goodid}`, {
goods_name: values.goods_name,
goods_number: values.goods_number,
goods_price: values.goods_price,
goods_weight: values.goods_weight
})
// console.log(data);
if (meta.status === 200) {
message.success(meta.msg)
setIsModalVisible(false);
getUserData()
} else {
message.info(meta.msg)
setIsModalVisible(false);
}
};
<Button type="primary" size="small" onClick={() => { showedit(record.goods_id) }}> <EditOutlined /> </Button>
{/* 修改弹出框 */}
<Modal title="修改商品" visible={isModalVisible} footer={null}>
<Form

labelCol={{ span: 4 }}

</Modal>删除商品
点击删除按钮传递一个id，然后请求删除接口即可
// 删除
const delGoods = async (e) => {
console.log(e);
let { meta } = await axios.delete(`goods/${e}`)
switch (meta.status) {
case 200:
message.success(meta.msg)
break;

message.warning("删除失败")
